Over 200 masked right-wing supporters, carrying placards with racist overtones, went on a rampage in the eastern city of Leipzig on Monday night, throwing fireworks, breaking windows and vandalizing buildings, police said.

Emotions are running high in German cities after gangs of young migrant men sexually assaulted women at New Year in mass attacks in Cologne and other towns.

The attacks have deepened public scepticism towards Chancellor Angela Merkel's open-door refugee policy and her mantra that Germany can cope with the 1.1 million migrants who arrived in the country last year. It has also fueled right-wing groups.

As roughly 2,000 anti-Muslim "LEGIDA" protesters marched peacefully in the city center, police said a separate group of 211 people walked through the southern Connewitz district before setting of fireworks, erecting barricades and vandalizing property. The top floor of one building caught fire.

In April, I began an email correspondence with an American I’ll call Susan (she prefers to remain anonymous), who has lived in China for 15 years while working in publishing. She currently resides in Beijing and also lived in a small town in Hubei province.

Susan came across our Change.org petition (325,000-plus signatures) asking Congress to “Keep Chinese Chicken Out of Our Schools and Supermarkets” and reached out to me. While she loves China and its people, Susan’s first-hand knowledge of China’s poor food safety practices leaves her deeply concerned about the prospect of American chicken being processed in China for consumption in the U.S.

To provide consumers with even more information about how a weak Chinese food safety system poses a real threat to Americans, I have compiled a Q&A excerpt from my often-startling correspondence with Susan.
